To determine the probability that exactly two of the five marbles are blue, we will use the rule of multiplication.
Let event A = the event that the first marble drawn is blue; and let B = the event that the second marble drawn is blue.
To start, it is given that there are 50 marbles, 20 of them are blue. Therefore, P(A) = 20/50
After the first selection, there are 49 marbles left, 19 of them are blue. Therefore, P(A|B) = 19/49
Based on the rule of multiplication:P(A ∩ B) = P(A)*P(A|B)P(A ∩ B) = (20/50) (19/49)P(A ∩ B) = 380/2450P(A ∩ B) = 38/245 or 15.51%
The probability that there will be two blue marbles among the five drawn marbles is 38/245 or 15.51%
We got the 15.51% by dividing 38 by 245. The quotient will be 0.1551. We then multiplied it by 100% resulting to 15.51%
Answer:
a. 24.5 $
b. 10.5 $
c. 7/10
Step-by-step explanation:
Given the original price of the sweater is: $ 35.
a) If you pay only of the price, then the actual amount paid is: = 24.5 $.
b) Total amount Saved = Actual price - Price you paid
Total Amount Saved =
= 10.5 $.
c) Fraction of the original price saved = Total amount Spent/Actual Price
Total amount Saved =
=
Lets say m is miles and h is hours
then according to your equation
m=50h
because after each hour 50 miles are increasing a constant change of 50
<u>Answer:</u>
The correct answer option is a) y =2.
<u>Step-by-step explanation:</u>
We are given the following equation and we are to find the solution of this equation:
Here, the expression is given in a modulus, which means that its value cannot be negative.
Ignoring the negative sign because of mod.
y = 2
